The tutorials moved faster than I did: building an agent that catches deprecated dependencies

Description and use

A developer built Release Radar, an agent that automatically checks dependency repositories for renames, archiving, or deprecation, providing warnings that traditional version‑comparison tools miss.

Problem

Tutorials and package names change faster than developers can keep up, causing legacy tools to break and dependencies to become deprecated or archived without obvious signals.

Outcome

Release Radar detects deprecated, renamed, or archived dependencies that version‑only tools miss, reducing the risk of running unsupported libraries and enabling timely migration.

Workflow

• 1. Uninstall conflicting CLI tools (bedrock-agentcore-starter-toolkit, npm @aws/agentcore).
• 2. Scaffold a new AgentCore project with the Strands Agents framework and Amazon Bedrock provider.
• 3. Implement a Strands tool (repo_status) that queries the GitHub API for repository info, handling authentication and rate limits.
• 4. Add logic to parse repository description, release notes, and archived status to determine BLOCKED, BEHIND, or OK verdicts.
• 5. Run the agent locally to validate deterministic logic.
• 6. (Future) Deploy the agent to AWS Bedrock AgentCore for scheduled execution.

Evidence

Tools already exist for outdated dependencies: Dependabot, Renovate, npm outdated, and pip list --outdated. They compare the version you pinned with the latest version, then report the difference.

Source

Number comparison cannot detect any of these. The evidence is written in plain English on the repository page. In the third case, someone has written a paragraph asking you to stop using the dependency.
